That's up to the committers adding them to be careful, but I of course
agree that the context is important.  IMV, we can do a slightly better
organization in "Asynchronous Behaviour".  First, backend_flush_after
is independent, and could just be first.

parallel_leader_participation can also be moved after
max_parallel_workers without impacting the readability nor impacting
the set of parallel-ish parameters grouped together.
